IR and Raman spectroscopy: monitoring immobilization of some anticancer organotin(IV) compounds on mesoporous silica

On demand | Presented live 9 April 2024

Abstract

The IR-ATR, IR transmittance and Raman spectroscopy techniques were used in monitoring the immobilization of newly synthesized compounds (4-O-acetyl ferulato)triphenyltin(IV) and (fenoprofenato)tributyltin(IV), showing anticancer activity, on MCM-41 and SBA-15 mesoporous silica nanostructures (MSN). The IR analysis of the synthesized tin(IV) compounds proved a monodentate binding of the carboxylic group to the Sn atom, using the splitting of the ν(COO) band in the IR spectrum. The IR-ATR spectra of the synthesized MSN were used to check the porosity of the synthesized materials on the basis of the changes of the Si-OH(H2O) and Si-O stretching vibration band profile. The immobilized organotin(IV) compounds in both MSN were analyzed and the success of the immobilization was monitored and discussed through the changes in the IR and Raman spectra.

Prof. Dr. Vladimir Ivanovski is a Full Professor at the Institute of Chemistry, Faculty of Natural Sciences and Mathematics, Ss. Cyril and Methodius University in Skopje, where he received his PhD. His main scope of scientific interest is in the field of IR and Raman spectroscopy. As a post-doc fellow of Alexander von Humboldt Foundation, he worked on models of reflectance and dielectric functions of single crystals with low symmetry. The last ten years he is particularly engaged in the surface modification of glass, and other materials and their investigation using IR, Raman spectroscopy, and other techniques.
Application tracks: EU-funded Research
